Origin and Habitat: Chihuahuan Desert of South Texas, in Brewster/Sanderson County and northern Mexico in Coahuila and Chihuahua.
Altitude: 700-1500 metres above sea level.
Habitat: Epithelantha bokeiSN|12641]]SN|12641]] is an edaphic specialist growing in dense groups on very specific calcareous strata on raised limestone hills, mountain top and ledges in xerophyllous scrub. It also grows on plains, on gravel mixed with earth containing a big amount of organic compounds from decayed leaves. It is locally abundant and it grows in many inaccessible areas, however some subpopulations are threatened by illegal collection.

Description: Epithelantha bokeiSN|12641]]SN|12641]]is a slow-growing mini cactus (usually solitary), with only 2-3 cm of stem height, covered so densely with closely appressed tiny white spines that the plants appear to be completely white and smooth to the touch.
Flower: Flowers are pale pink or yellowish, very delicate, appearing in July.
Fruits: Fruits are smooth, approximately 1 cm long, bright red, edible and enjoyed by birds.
Remarks: In periods when water is available it is an almost completely rounded cactus. In drought periods, and during winter rest, plants shrinks and draw back down to ground level, to conserve moisture.

Cultivation and Propagation: Although regarded as a choice and difficult plant, in cultivation it is relatively easy, but very slow growing.. These plants need very coarse potting soil that drains well (rot prone). Waterings should be rather infrequent, to keep the plant compact and not become excessively elongated or unnatural in appearance.
Frost Tolerance: Depending on the variety, it will take -5? C (or less) (Temperature Zone: USDA 8-11).

Sun Exposure: It requires strong sun to part sun to develop good spinal growth, but some summer shade in the hottest hours of the day is beneficial. Assure a good ventilation.
Propagation: It can be reproduced both by seeds and cuttings, but it is often grafted because difficult and slow to grow on its own roots. Older specimens shoot tillers from under tubercles, so they can be grafted, which is a much easier way of propagation than sowing. Young seedlings are tiny and they need several years to reach adult size, and require careful watering.
